raised border, and set so close to each other that they give a 

 frosted appearance to it. There is a space between the border- 

 and the wing. In a few cases the wing, or keel, dies away almost 

 as soon as it reaches the body of the test. Over forty are on the- 

 slide. Locality : Chiefly Nos. 3, 7, 18, 26, 28, 30.

PI. 19, fig. 10. Bearing in mind the form of the test and the 

 raised border, I think this may be looked upon as a weak form 

 of L. formosa (Sch wager) var comata Brady. There is a narrow 

 space between the border and the keel, which often either 

 splits towards the base or ends in tubular projections. The 

 body is striated. All the tests are imperfect and the split 

 wings are clogged with shell-growth. Localit>/ : Chiefly Nos.. 

 1, 2, 17, 18. Frequent. 



PI. 19, fig. 11. The lower end of the test is only slightly 

 compressed, but the compression becomes more marked as the 

 orifice is approached. The keel, commencing at the orifice, 

 becomes less pronounced as it proceeds towards the base. Sur- 

 rounding the body of the test, on either face and at a short 

 distance from the keel, is a raised border, perforated by tubuli. 

 On both edges of the test there are two costae, one on either 

 side of the keel, between it and the border. The tests are 

 small and a good deal of shell-growth, or debris, is found on 

 most of the examples between the costae, which interferes with 

 their definition. Locality : Nos. 3, 17, 19. Rare. 



PI. 19, fig. 12. This appears to be the trigonal form of the^ 

 above, and occurs more frequently and at numerous stations. 

 Locality : Nos. 1, 3, 9, 11, 19, 26, and a few other stations.

This occurs in many forms, typical and otherwise, and at various 

 stations.
